Name: Tangential Acceleration Introduction with Example Problem - Mints on a Turntable Category: Rotational Motion Date Added: 2017-08-13 Submitter: Flipping Physics
Tangential Acceleration is introduced and visualized. Example problem is worked through. We even relate arc length, tangential velocity, and tangential acceleration via the derivative! Example: A record player is plugged in and uniformly accelerates to 45 revolutions per minute in 0.85 seconds. Mints are located 3.0 cm, 8.0 cm, and 13.0 cm from the center of the record. What is the magnitude of the tangential acceleration of each mint?

A record player is plugged in, uniformly accelerates to 45 revolutions per minute, and then is unplugged. The record player (a) takes 0.85 seconds to get up to speed, (b) spends 3.37 seconds at 45 rpms, and then (c) takes 2.32 seconds to slow down to a stop. What is the average angular acceleration of the record player during all three parts?
